Dozens of councils have been sacked and 19 new ones created under the NSW government's controversial amalgamations plan.
The government also plans to merge nine other councils pending the outcome of legal action taken over the proposals.
"I strongly believe that we have taken decisions that are in the interest of ratepayers from one end of the state to the other," Premier Mike Baird said.
Administrators and interim general managers were on Thursday appointed to each of the new councils, and they will remain in place until council elections take place in September next year.
Each new council will receive up to $10 million to meet the costs of merging, while $15 million will also be given for new community infrastructure.
"There have been many groups across the state that don't want to see change," Mr Baird said.
"(But) I think having smaller head offices and having more money that goes towards childcare, parks, sporting facilities, frontline services - I think that's a great thing for the state," he said.
Local Government Minister Paul Toole said the mergers would not affect the day-to-day business for councils.
New rules to clamp down on dishonest councillors and a $2500 cap on political donations for council elections were also announced as part of the reforms.
This includes moves to close a loophole in legislation that allows council officials to vote on planning matters in which they or a relative have a pecuniary interest, where the permissible use of the land is not being altered.
"I think this is a message about saying to councillors or anyone thinking about running for a councillor, don't consider it if you are thinking about lining your pockets," Mr Toole said.
The premier announced plans to overhaul the state's councils in December last year after asking councils to prove their "fitness" for the future.
The plan was to reduce 152 councils in NSW down to 113 but that will now become 115.
A review of the merged councils will be conducted in four years.
